Axion Inflation with a Massive Abelian Gauge Field
Ricardo Z. Ferreira, Alessio Notari, José Jaime Terente DÃaz
The paper studies how an axial coupling between an inflaton (axion) and a massive Abelian gauge field can cause tachyonic amplification of one helicity, analyzes the resulting back…

Domain walls through different cosmologies
I. Dankovsky, D. Gorbunov, S. Ramazanov +1
The paper uses lattice simulations to study how domain wall networks evolve under various early‑universe expansion histories, showing that the particle horizon largely determines w…

Speed of sound peak in two-color dense QCD: confronting effective models with lattice data
Arthur E. B. Pasqualotto, Dyana C. Duarte, Ricardo L. S. Farias +1
The paper investigates the peak in the speed of sound seen in lattice simulations of two‑color, two‑flavor QCD at finite chemical potential and shows that an NJL model enhanced wit…
